Several domestic USautomobile manufactures have committed to develop vehicles using hydrogen.

(They had previously committed to producing electric vehicles in California, a program now defunct at their behest.)

Critics argue this "commitment" is merely a ploy to sidestep current calls for increased efficiency in gasoline and diesel fuel powered vehicles.

Some hospitals have installed combined electrolyzer-storage-fuel cell units for local emergency power.

These are advantageous for emergency use due to their low maintenance requirement and ease of location compared to internal combustion driven generators.

The North Atlantic island country of Iceland has committed to becoming the world's first hydrogen economy by the year 2050.

Iceland is in a unique position: at present, it imports all the petroleum products necessary to power its automobiles and fishing fleet.

But Iceland has large geothermal and hydroelectric resources, so much so that the local price of electricity actually is lower than the price of the hydrocarbons that could be used to produce that electricity.
